It said first lower clamping member, apparatus according to any one of the first of claims 1, which is arranged to adequately support the first end of the strip member 4. The first lower clamp member includes a lower cutting edge, and the device moves the first end of the first strip member along and in cooperation with the lower cutting edge. apparatus according to any one of claims 1 further comprising a first knife is arranged to cut 5. The apparatus of claim 6 , wherein the first knife is movable along the lower cutting edge in a first cutting direction across or perpendicular to the butt splice direction. 8. The apparatus according to claim 6 or 7 , wherein the lower cutting edge projects beyond the first upper clamp member in the butt splice direction toward the second clamp over the first overlap distance. . 9. The apparatus of claim 8, wherein the entire lower cutting edge projects beyond the first upper clamp member in the butt splice direction toward the second clamp over the first overlap distance. . Said first knife from the case of moving the butt splice direction, the first of the first claim 6 which is arranged to be retracted to the standby position within the knife deviates from the first clamp The apparatus according to any one of 9 . The second upper clamp member includes an upper cutting edge, and the device moves the second end of the second strip member along and in cooperation with the upper cutting edge. to cutting apparatus according to any one of claims 1 to 10 further including a second knife is arranged. 12. The apparatus of claim 11 , wherein the second knife is a lower knife that is movable in a second cutting direction across or perpendicular to the butt splice direction along the upper cutting edge. 13. Apparatus according to claim 11 or 12 , wherein the upper cutting edge projects beyond the second lower clamp in the butt splice direction towards the first clamp over the second overlap distance. . 14. The apparatus of claim 13, wherein the entire upper cutting edge projects beyond the second lower clamp in the butt splice direction toward the first clamp over the second overlap distance. . The apparatus, wherein for the first clamp driving toward the second clamp device according to any one of the first of claims 1, which comprises a drive 14. 16. A device according to any one of the preceding claims, wherein the device comprises a second drive for driving the second clamp towards the first clamp. It said first end is the distal portion of the first strip member, and said second end, one of claims 1 to 16, which is the rear end portion of the second strip member A device according to any one of the above. The first strip member and the second strip member are arranged to be transferred in a transfer direction, and the first clamp is located upstream of the second clamp in the transfer direction. The apparatus of claim 17 . The first strip member and the second strip member include a first liner and a second liner, respectively, and the first liner is formed from the first end prior to butt splicing. Arranged to be peeled and applied on the second liner in the second strip member after butt splicing, the device at the butt-spliced end after butt splicing 19. An apparatus according to claim 17 or 18 , further comprising a sealer for welding the first liner to the second liner at or near the second strip member. 20. A method for butt splicing a strip member for a tire component using the apparatus according to any one of claims 1 to 19 , wherein the method comprises the first lower clamp member and the second upper clamp. Moving the first clamp and / or the second clamp into the butt splice position such that members overlap each other in the butt splice direction. The first strip member and the second strip member include a first liner and a second liner, respectively, and the first liner is formed from the first end prior to butt splicing. Arranged to be peeled and applied on the second liner in the second strip member after butt splicing, the device at the butt-spliced end after butt splicing Or in the vicinity of the second strip member, further comprising a sealer for welding the first liner to the second liner, wherein the method includes the first liner prior to butt splicing. The first liner is peeled off from the first end and after the butt splicing, the first liner is removed from the second liner. Applied on further after the butt splicing, in the first weld at or near on its butt splice location, further comprising the step of welding the first liner to said second liner, claim 20 The method described in 1.
